1933. E. E. SAXTON COLLAPSIBLE UMBRELLA Original Filed Au 27, 1928 2 Sheets-Sheet Patented Feb. 7, 1933 UNITED STATES ELLSWORTH E. SAXTON, F BREMERTON, WASHINGTON COLLAPSIBLE UMBRELLA Application filed August 27, 1928, Serial No. 302,240. Renewed lune 29, 1932.

My invention consists of an umbrella so constructed as to be carried, when not in use, in a collapsed form, and withina tubular casing of comparatively short length, which may when desired be drawn from its casing and expanded to form an umbrella of a size to give practical protection, and with a handle of convenient length.

The object of my invention is to produce a collapsible umbrella of a practical type, collapsible as to length as well as foldable.

The invention includes many features of construction which contribute to the desired result. Its scope will be more specifically defined by the claims which terminate this specification.

In the accompanying drawings I have illustrated my invention as embodied in a preferred construction.

Figure 1 shows the umbrella when expanded and raised.

Figure 2 is a side view of the umbrella in extended but unopened position, certain of the parts being in section and a partially opened position of the ribs shown in dotted lines.

Figure 8 is alongitudinal sectional view of the umbrella when in completely folded and telescoped condition.

Figure 4 illustrates the exterior appearance when in collapsed and carrying position.

Figure 5 is a top view, the stem being in cross section and the adjacent ends of the ribs shown.

Figure 6 is a cross section of the telescoping bars taken at the points where the friction catches are located.

In accordance with my invention the urnbrella ribs are each made of two telescoping sections, 1 and 2, so that each rib is collapsible, by the telescoping, to a length but little more than half that of the composite rib when the umbrella is opened for use. The upper or inner sections 1 are pivotally 45 mounted upon the stem in any suitable manner, as by pivoting upon a collar or tip member 30, carried by the upper stem section 3.

As illustrated in Figure 6, the rib sections are of a rectangular tubular shape. This 50 rectangular section is however, not an essential. As illustrated, the enveloping section 1 is pivoted upon the tip 30, in which case it is slotted on its inner face, so that the brace 5, which is pivoted to the inner end of the extension section 2,1naypass well up the slot towards the stem 3 and tip 30 during folding. The cover 6 is secured to the ribs in any suitable mannen The stem is composed of two telescoping tubes 3 and 4. A double ended spring catch or detent, similar to those ordinarily used to engage with the usual sliding collar, for holding umbrellas opened or closed, may be placed within the inner tube 3, and have its ends 7 and 70 projectible through slots 40 in the tube 3 toenter slots in the outer tube -4, these ends or spring dogs 7 and 70 functioning in the manner common in standard umbrella constructions.

The lower ends of the braces 5 are pivoted upon a collar 50, the counterpart of which is found in all standard umbrellas, mounted to slide upon the lower tube 4 of the stem. The outer casing 8, is a tube, open at one end, and of a size to slip over the umbrella when in collapsed and folded condition, as is shown in Figure 3. I have provided it with a threaded sleeve or interiorly projecting boss 80 designed to screw upon the threaded lower end of the lower stem section 4, both when placed about the folded umbrella and in reversed position, to serve as a handle, as shown in Figure 2, when the umbrella is opened.

When the umbrella is collapsed and folded, as shown in Figure 3, the cover 6 is folded upon itself, as shown at 60. To open the umbrella the enveloping casing tube 8 is first removed, reversed in position, and secured upon the lower end of the stem section 4.

The stem sections are then drawn out, which also draws out the telescoping rib sections. The rib sections are provided with any form of friction catches to hold them at the two points, when completely telescoped and when completely extended. Such catches may be slight projections and recesses,

pressed into the metal at spaced points, such as are shown in somewhat exaggerated dimensions at 12 in Figure 6.

When the telescoping sections are drawn out to the proper point the friction catches are engaged, so that when the collar 50 is slid along the stem section 4: the ribs are opened out, as is indicated in dotted lines in Figure 2. The stem section 3 is drawn out, relative to the section 4, to the point where the spring detent 7 0 in the bottom of the slot 40 operates to hold them in adjusted position, or as shown in Figure 1. The detent 7, in this position, may be engaged beneath the collar 50 to hold the ribs in extended position.

What I claim as my invention is:

1. In a folding umbrella having a stem and runner thereon, two-part ribs, each inner rib section being pivoted to the stem, and being of U-shape in cross-section, opening towards the stem, the associated outer rib section being likewise of U-shape in crosssection, opening towards the stem, and telescoping within the corresponding inner rib section, a. brace pivoted by its outer end to the inner end of the outer rib section, the pivot being so disposed that the brace lies, when folded, within the cross-section of the inner rib section, the inner end of said brace being pivoted to said runner.

2. A folding umbrella as in claim 1, the side flanges of the outer rib section being omitted at its outer end, to closely embrace the runner when in folded position.
